Jovial young Physicist Ernest Orlando Lawrence has an 85-ton atom smasher at Berkeley, Calif. Intrigued by the Lawrence cyclotron, promoters of the Golden Gate International Exposition asked if they could borrow it to smash atoms for next year's fair. Physicist Lawrence, who was deep in experimentation, pointed to the protective wall of six-foot-high water tanks surrounding the cyclotron, explained that neutrons flying free as hail around an exhibition room might settle in the tissues of spectators, even render them sterile. The exposition officials hastily retired, and last fortnight they hatched plans to exhibit a model...
...atom-with library, conference room and tea room-will eat up $500,000. Another $50,000 went into a 36-ft. high-voltage atom-smasher. This hurls atomic bullets at controlled energies up to 2,000,000 electron-volts. Still another $30,000 was laid out for a cyclotron-an atom-smashing machine of the type invented by the University of California's Ernest Orlando Lawrence, which spirals atomic bullets up to huge speeds by repeated electrical kicks...
...time in some region or other of the universe. Hannes Alfven of Sweden's Upsala University holds that the rays are free-moving particles in space accelerated to cosmic ray energies by the magnetic fields of spinning double stars - somewhat as the man-made machine called the cyclotron speeds up atom-smashing particles to high velocities by means of repeated electrical pushes...
...neutron rays, and also the emanations from artificially radioactive substances, may turn out to be beneficial instead of harmful if artfully managed. Lately the biological and medicinal possibilities of cyclotron products have loomed increasingly large on the scientific horizon. In a malodorous room near the cyclotron chamber at Berkeley are stacks of cages containing white rats, labeled by splotches of blue, yellow or pink paint on their backs. These animals have been made cancerous by implantations of cancerous tissue. Preliminary experiments tend to show that neutron bombardments have a selective effect on cancer cells five times as strong as that...
During the past month workmen have been laying the concrete floor of a big new laboratory next to the old building. In this a tremendous cyclotron with a 220-ton magnet will be installed, hurling deuterons at 12,000,000 to 20,000,000 volts, alpha particles at 24,000,000 to 40,000,000. When completed the new building will contain biochemical laboratories and a clinic. San Francisco's late William Henry Crocker gave $75,000 for this project, the Chemical Foundation $68,000, Dr. Lawrence estimates that he needs about $35,000 more. Designer...
